| Investment Objective: |
Columbia Research Enhanced Core Premium Income ETF seeks high income, with a secondary objective of capital appreciation. The Fund is an actively managed exchange-traded fund (ETF) that, under normal circumstances, pursues its investment objective by investing in a portfolio of stocks of U.S. large and mid capitalization companies (those with market capitalizations in the range of the companies in the Russell 1000 Index, which ranged between $134.5 million and $4.2 trillion as of March 31, 2026), and by incorporating call option strategies. The Fund's call option strategies include writing (selling) call options on U.S. equity market indexes or on other ETFs that passively track (or seek the investment performance of) U.S. equity market indexes, such as the S&P 500 Index and the Russell 1000 Index (each, an Options Index). The Fund seeks to generate high monthly income from premiums earned from writing (selling) call options and dividends received from the Fund's holdings in stocks of U.S. large and midcapitalization companies. The Fund also buys call options on Options Indexes to provide the potential for upside U.S. equity market participation when the Options Index appreciates. |
